  • Glaciers form when snowfall is greater than snowmelt and snow changes into compact granular ice over time.
  • Snow fields are large areas permanently covered with snow.

2. Movement of Glaciers

  • Lious Agassiz proved in 1834 that glaciers move.
  • He used pegs placed across the width of a glacier and found that the middle pegs moved faster than the side pegs.
  • The rate of glacier movement is maximum in the middle and decreases towards the sides.

  • There are four main types of glaciers: continental glaciers, ice caps, piedmont glaciers, and valley glaciers.
  • Continental glaciers are huge masses of ice covering vast areas and spreading outward in all directions.
  • Ice caps are covers of snow and ice on mountains from which valley or mountain glaciers originate.
